swiftwater rescue

I spent the weekend at the Russell Fork taking a swift water rescue class. We practiced tying knots, handling rope, swimming whitewater, and setting up mechanical advantage systems. Our lead instructor, Mike Morrow, stimulated a foot entrapment in this scenario. Would you know what to do in this situation?

Two students work to evacuate an unconscious victim.
Team work and communication are crucial to scene management. Paddlers of all skill levels should take some type of water rescue class. Veterans with years of experience get rusty without practicing rescue techniques. The American Canoe Association sanctions courses around the country. The Hail Mary (WRSI throwbag) got rave reviews from the students. Several of us had them and they were consistently the most accurate ropes. I did manage to have a little fun on the side.
